over beds of plants grown in the open-air,

the main object being to rovide asprin- 'kling-apparatus which shall every efficient and reliable in its 0 erat-ion, easily and convenientlycontrolle and at the same time shall be inex ensive to construct.

To the 811( the invention consists essentially of a suitably supportedwater-conducting ipe adapted to move over the plant-be and provided withspraying-v means, means for supplying the pipe with water underpressure, and means for imparting movementto said pipe.

The invention also consists in certain novel details of construction andarrangement of the component parts of the sprinkling-apparatushereinafter fully described and set forth in the claims.

In, the accompanying drawings Figure 1 represents a transverse sectionof a greenhouse equipped with the plant-sprinkling alpparatus'embodyingmy invention; Fig. 2 sows a plan view of the usual plant-racks of thegreen-house, and illustrates the arrangement of the oscillating pipeswhich conduct the water 'over the plant-racks, and showing the mechanismfor "transmitting movement from the main sprinkling-pipe to a branchsprinkling-pipe arranged at an angle thereto; Fig. 3 is an enlargeddetail side view of the forward end portion of a main sprinkling-pipe,-in this instance designed to be extended lengthwise of the green-houseor a bed of plants located oute of-doors, and showing part of themechanism fior oscillatin said pipe; and Fig. 4 is an enlarged deta'view showing the waterconneotion between a main sprinkling-pipe andbranch sprinkling-pipe, and also showing a mechanism for transmittingmotion from the former to the latter.

Referring to the drawings AA denote frame members of the green-housewhich may be of any well known construction.

BB represent the usual longitudinally disposed plant-racks which supportthe beds of plants and extend along the sides of the green-house, and Brepresents -a similar rack which in some greenhouses is arranged acrossone end thereof.

However, the arrangement of these plantracks is immaterial to theconstruction and operation of my sprinkling-apparatus. Said apparatuscomprises a main oscillating sprinkling-pipe 1 which extends lengthwiseof the plant-rack B- and may be siipported in any suitable andconvenient manner, but I preferably mount-said pipe on brackets 22V-fastened to the sides oil posts 33 and arranged centrally over ,system,I-employ a rotary pump 4 for supplying the pipes with water, and at thesame time utilize the said pump as a motive ower for operating themechanism to oscilate the pipes as will be shortly explained. Thepump isprovided with the usual inletpipe 5- leading from a service-pipe (notshown), and to said inlet-pipe is connected an ordinary valve '6 for oening and closing the said pipe as may be esired.

7, denotes the discharge-pipe of the urn which is connected by means ofa exi le pipe 8 to a pipe 9 secured in the forward end of the mainsprinklingiple 1 for delivering the water thereto. FV ere two of saidmain sprinkling-pipes 11 are employed, as shown in the present case, itis obvious that two flexible pipes .88are to be rovided. These pipes 88are preferailly connected by means of the usual and well known couplingsto a IF-pipe 9 connected to the pipe forated tips as indicated at 22.'

7 of the pump, said T-pi e being rovided with valves 1010 or contro ingthe discharge through the pipes 11-.

Any'suitable mechanism may be employed for transmitting oscillatorymotion fromthe pump to the main sprinkling-pipe 1'. The mechanism showncomprises a short crank 1l fastened to the shaft of the pump andconnected by means of a rod 12 to a lever 13 fastened to the pipe -9*which is rigidly secured in the forward end of the pipe 1 as illustratedin Figs. 1 and 3.

14 denotes a supplemental or branch I sprinkling-pipe extendin centrallyand horizontally over the end p ant-rack B of the green-house anddisposed at right angles to and in the planeof the pipes 11. Said branchpipe is journaled in brackets 13 13 secured to the sides of posts -14 14Any suitable mechanism may be employed for oscillating the branchsprinkling-pipe i sprinkling pipe to the branch sprinklingpipe by meansof a flexible pipe 18 connected by suitable cou lings 19-20. Thecoupling 19 is (pEeferably attached; to the shaft 17, an the coupling+20 is applied to the adjacent end of the pipe -14- v as shown in Figs.2 and 4.

Each of the sprinkling-pipes 114 is provided with spraying means whichmay be of any suitable form. These sprayers consist preferably ofdownwardly extending flaring nipples 2121 detachably secured in thepipes and provided with per- It is obvious that said tips may be ofvarious styles and may be provided with perforations of difierentsizesaccording to the density or character of the spray desired. ,I

prefer however, to provide interchangeable Water-supply pipe, branch-pies leading.

from the supply pipe to the oscil atory pipes,

and means actuated by the flow of water from the supply pipe andimparting motion to the oscillatory pipes.

2. A plant-sprinkling apparatus comprising a suitably journaledoscillating pipe pro vided with a series of sprayers, a rotary waterpump having a suitable source of supply and discharging the water intosaid pipe, a crank secured to the shaft of the pump, a lever rigidlyconnected at one end to the pipe, and a rod connecting the opposite endof the lever to the crank for transmitting oscillatory motion from thepump to the pipe as set forth.

3. An apparatus for the purpose specified comprising two oscillatorysprinkling-pipes, a water-pump having a suitable source of supply anddelivering 'the water under pressure to said pipe, mechanism actuated bythe pump for imparting oscillating movement to one of said pipes, andmechanism for transmitting like motion from one pipe to the other as setforth.

0 4. An apparatus for the purpose specified comprising a mainoscillatory sprinklingpipe and a branch oscillatory sprinkling-pipedisposed at an angle to the main pipe, a

rotary pump for delivering Water under pressure to the main pipe, asuitable flexible water-connection between the two pipes, mechanismactuated by the pump for imparting oscillations to the main pipe, andgears transmitting like motion from the latter ipe to the branchsprinkling-pipe as set fort JOHN W. LISCHER.
